535i's (N54) don't have MAF sensors but TMAP sensors which are located on the charge pipe, is that correct? If so does the TMAP sensor need to be cleaned ever, from what I understand it detects pressure so I'm guessing it won't make a difference?

 

I need to do this, but I'm scared. May try it if I get confident

 

had some hesitation issues lately, followed this step with some MAf cleaner from autozone, in 10 minutes had it off and cleaned, drives perfect! barely used any of the cleaner, so easy i will clean every one in a while. ill add some fuel injector treatment as well.
